Adam Powell 5dd072d884 Allow swipe down to dismiss for ResolverDrawerLayout
Let the user swipe the intent resolver UI off of the screen to get rid
of it. So satisfying!

Also fix a bug where transitioning between touching the area outside
of the drawer to the drawer itself would misbehave or otherwise
dismiss when it shouldn't.
